Problems solved by technology

[0003] When the weather is cold, lithium batteries often fail to charge at low temperatures, because the low temperature will cause the electrolyte inside the lithium battery to become viscous, or even condense, resulting in slow charging. Until regular testing, this will lead to potential safety hazards in lithium batteries, and accidents of lithium battery explosion and combustion still occur, so automatic detection of lithium battery quality can reduce the occurrence of accidents

Abstract

An automatic constant-temperature lithium battery auxiliary device disclosed by the present invention comprises a protection box, a charging head, a heat dissipation groove and a battery body, a protection mechanism is mounted on the inner wall of the protection box below the heat dissipation groove, a constant-temperature mechanism is mounted on the protection mechanism, and a flame-retardant mechanism is mounted on the inner wall of one side of the protection box. A limiting mechanism is installed on the surface of one side of the protection box, and a sealing rotating plate is installed in the heat dissipation groove through a rotating shaft. Through the arrangement of the structure, the constant-temperature mechanism can take away heat on the surface of the battery body, so that the battery body is in a normal-temperature charging environment, and when the temperature of the battery body exceeds the normal temperature range of the lithium battery, the switch tube is started to trigger the electromagnetic valve to work, and cooling water in the liquid box and the limiting cooling tube is guided out; the problem of high temperature of the battery body can be solved, spontaneous combustion and combustion explosion can be avoided, the charging temperature can be increased, and the viscosity of the electrolyte can be reduced.

Description

technical field [0001] The invention relates to the technical field of lithium battery auxiliary equipment, in particular to an automatic constant temperature lithium battery auxiliary device. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries are widely used in trams. Through assembly, multiple lithium batteries are electrically connected and combined into large blocks. Battery; [0003] When the weather is cold, lithium batteries often fail to charge at low temperatures, because the low temperature will cause the electrolyte inside the lithium battery to become viscous, or even condense, resulting in slow charging. Until regular testing, this will lead to potential safety hazards in lithium batteries, and accidents of lithium battery explosion and combustion still occur, so automatic detection of lithium batter...
